------- Additional Comments From graham@wyenet.net  2005-10-13 12:50 -------
Thanks, here is the ssl.conf file I am using to test the 64bit build, its a 
copy from our of our 'production' servers which are currently on a 32bit build 
of Apache 2.0.54, I've xxx'ed out part of the pathnames as they appear on the 
production server, but apart from that the config file is 'as is'

Building the same source tree in 32 bit resolves the warning, but as soon as I 
compile into 64bit I have the problem. 

My configure is /
./configure --enable-modules=most --enable-mods-shared=all --enable-so --
enable-ssl=/usr/local/ssl --enable-ssl=shared --enable-suexec --with-suexec-
caller=xxx --with-suexec-docroot=/xxx/xxx --with-suexec-
logfile=/var/log/suexec.cgi.log

When compiling with GCC, in 64bit, im using CFLAGS=-mcpu=ultrasparc -m64 -O3, 
and with Sun Studio im using CFLAGS=-Xa -xtarget=ultra2 -xarch=v9a -xvis -xO4 -
xspace -xdepend

Both compilers successfully build both the 32bit, and 64bit versions, both the 
GCC and Sun CC 32 bit builds have no errors in the error_log, but the GCC and 
Sun CC 64bit builds both exhibit the same warnings in the error_log.

As I reported initialy the server continues to startup after the warning, and 
the SSL sites are functioning 100%, with the correct certificate attached to 
the sites as I would expect.

Apart from this one warning in the error_log, the 64bit build is performing 
spectacularly well, on identical 500mhz Netra AC200 servers the 32bit build is 
pumping out 350 requests per second according to an AB test on a very simple 
static html file, the same test on the 64bit build is giving 400 
requests/second.

I initially tested the 64bit build using a production httpd.conf with 200 
virtual *:80 NameVirtual hosts, but to simplify testing I replaced it with the 
default httpd.conf that is installed after the initial make install, so the 
only 'modified' config file is ssl.conf which I have added below.

#   Server Certificate:
#   Point SSLCertificateFile at a PEM encoded certificate.  If
#   the certificate is encrypted, then you will be prompted for a
#   pass phrase.  Note that a kill -HUP will prompt again.  Keep

#   Server Certificate Chain:
#   Point SSLCertificateChainFile at a file containing the
#   concatenation of PEM encoded CA certificates which form the
#   certificate chain for the server certificate. Alternatively
#   the referenced file can be the same as SSLCertificateFile
#   when the CA certificates are directly appended to the server
#   certificate for convinience.
#SSLCertificateChainFile /xxx/xxx/conf/ssl.crt/ca.crt

#   Certificate Authority (CA):
#   Set the CA certificate verification path where to find CA
#   certificates for client authentication or alternatively one
#   huge file containing all of them (file must be PEM encoded)
#   Note: Inside SSLCACertificatePath you need hash symlinks
#         to point to the certificate files. Use the provided

#   Note: Inside SSLCARevocationPath you need hash symlinks

#   Client Authentication (Type):
#   Client certificate verification type and depth.  Types are

#   number which specifies how deeply to verify the certificate
#   issuer chain before deciding the certificate is not valid.
#SSLVerifyClient require
#SSLVerifyDepth  10

#   Access Control:
#   With SSLRequire you can do per-directory access control based
#   on arbitrary complex boolean expressions containing server
#   variable checks and other lookup directives.  The syntax is a
#   mixture between C and Perl.  See the mod_ssl documentation
#   for more details.
#<Location />
#SSLRequire (    %{SSL_CIPHER} !~ m/^(EXP|NULL)/ \
#            and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd." \
#            and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"} \
#            and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \
#            and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20       ) \
#           or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
#</Location>

#   SSL Engine Options:
#   Set various options for the SSL engine.
#   o FakeBasicAuth:
#     Translate the client X.509 into a Basic Authorisation.  This means that
#     the standard Auth/DBMAuth methods can be used for access control.  The
#     user name is the `one line' version of the client's X.509 certificate.
#     Note that no password is obtained from the user. Every entry in the user
#     file needs this password: `xxj31ZMTZzkVA'.
#   o ExportCertData:
#     This exports two additional environment variables: SSL_CLIENT_CERT and
#     SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
#     server (always existing) and the client (only existing when client
#     authentication is used). This can be used to import the certificates
#     into CGI scripts.
#   o StdEnvVars:
#     This exports the standard SSL/TLS related `SSL_*' environment variables.
#     Per default this exportation is switched off for performance reasons,
#     because the extraction step is an expensive operation and is usually
#     useless for serving static content. So one usually enables the
#     exportation for CGI and SSI requests only.
#   o CompatEnvVars:
#     This exports obsolete environment variables for backward compatibility
#     to Apache-SSL 1.x, mod_ssl 2.0.x, Sioux 1.0 and Stronghold 2.x. Use this
#     to provide compatibility to existing CGI scripts.
#   o StrictRequire:
#     This denies access when "SSLRequireSSL" or "SSLRequire" applied even
#     under a "Satisfy any" situation, i.e. when it applies access is denied
#     and no other module can change it.
#   o OptRenegotiate:
#     This enables optimized SSL connection renegotiation handling when SSL
#     directives are used in per-directory context.

#   SSL Protocol Adjustments:
#   The safe and default but still SSL/TLS standard compliant shutdown
#   approach is that mod_ssl sends the close notify alert but doesn't wait for
#   the close notify alert from client. When you need a different shutdown
#   approach you can use one of the following variables:
#   o ssl-unclean-shutdown:
#     This forces an unclean shutdown when the connection is closed, i.e. no
#     SSL close notify alert is send or allowed to received.  This violates
#     the SSL/TLS standard but is needed for some brain-dead browsers. Use
#     this when you receive I/O errors because of the standard approach where
#     mod_ssl sends the close notify alert.
#   o ssl-accurate-shutdown:
#     This forces an accurate shutdown when the connection is closed, i.e. a
#     SSL close notify alert is send and mod_ssl waits for the close notify
#     alert of the client. This is 100% SSL/TLS standard compliant, but in
#     practice often causes hanging connections with brain-dead browsers. Use
#     this only for browsers where you know that their SSL implementation
#     works correctly.
#   Notice: Most problems of broken clients are also related to the HTTP
#   keep-alive facility, so you usually additionally want to disable
#   keep-alive for those clients, too. Use variable "nokeepalive" for this.
#   Similarly, one has to force some clients to use HTTP/1.0 to workaround
#   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
#   "force-response-1.0" for this.
#SetEnvIf User-Agent ".*MSIE.*" \
#         nokeepalive ssl-unclean-shutdown \
#         downgrade-1.0 force-response-1.0

#   Per-Server Logging:
#   The home of a custom SSL log file. Use this when you want a
#   compact non-error SSL logfile on a virtual host basis.

#          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"
